What is the steering angle provided by the rudder pedals?

1. 10º in either direction

2. 5º in either direction

3. 7º in either direction

4. 15º in either direction

The correct answer is: 7º in either direction

The steering angle provided by the rudder pedals being 7º in either direction is based on standard practices for many aircraft designs. In general aviation, a limit of around 7º allows pilots to maintain controlled directional movements during taxiing and takeoff, ensuring effective steering response without compromising stability. This steering capability is especially important during ground operations, as it allows for manageable and predictable movement in various conditions. Limiting the steering angle helps prevent oversteering, which could lead to loss of control on the ground. In contrast, the other options reflect less typical values for the rudder pedals' steering capabilities. For example, both larger (10º, 15º) and smaller (5º) angles might not provide the desirable balance of control and stability needed during ground operations in most aircraft designs. Therefore, 7º represents a practical standard for such operations, making it the correct choice.
